Comparison of Urea-Phosphate with other available NP Based Fertilizers for Phosphorus Effect on Maize Growth Parameters

Abstract

To maintain the production of crop and fertility of soil, balanced fertilizers are required. The use of fertilizer and their ratio is investigated as improper ratio and use of fertilizer because yield lose. In current experiment, urea-phosphate fertilizer was compared with other phosphorus and nitrogen containing products like diammonium phosphate (DAP) and nitro-phos. For this purpose, an experiment was carried out in randomized block design on research farm to test the different phosphorus containing products on 13 studied attributed which includes Plant height, Number of leaves per plant, growth rate of plant, cob length, number of grain lines per cob, number of grains per cob, biological yield, grain yield, 1000 grain weight, harvest index, photosynthesis rate, transpiration rate and sub-stomatal CO2 conductance. The results revealed that when urea-phosphate applied at recommended ratio, the plants showed best results as compared to the nitro-phos and diammonium phosphate (DAP). The urea-phosphate has low pH which increase the efficiency of N and P by fixing the phosphorus fixation and ammonium volatilization. Thus, the use of urea-phosphate may improve the production of the crop and soil fertility with enrich efficiency of N and P and may reduce the environmental health and safety
